GAP Cotton classic trench coat size small

I’m reposhing this classic trench coat made by Gap. I love it, but alas, it’s a bit too small for me. It’s in excellent used condition with one small mark on the body. See picture where I’ve pointed it out with my finger. It really is quite minor, I can’t tell if it’s dirt or an actual faint mark on the fabric. 100% cotton exterior. Polyester lining on body. Size small. Has all the classic finishes: belt, decor at shoulder and cuffs, etc. Approximate measurements (in inches): Pit to pit: 17 Sleeve length (from shoulder seem to cuff): 24 Body length: from bottom of collar to bottom of garment: 33.5 Shoulder (from seam to seam): just under 14 My home is pet free, smoke free.
